Temporary Anchorage Device

Objective. To find out the success rate of miniscrew implants in the National Dental Centre of Singapore (NDCS) and the impact of patient-related, location-related, and miniscrew implant-related factors.Materials and Methods. Two hundred and eighty-five orthodontic miniscrew implants were examined from NDCS patient records. Eleven variables were analysed to see if there is any association with success. Outcome was measured twice, immediately after surgery prior to orthodontic loading (T1) and 12 months after surgery (T2). The outcome at T2 was assessed 12 months after the miniscrew’s insertion date or after its use as a temporary anchorage device has ceased.Results. Overall success rate was 94.7% at T1 and 83.3% at T2. Multivariate analysis revealed only the length of miniscrew implant to be significantly associated with success at both T1 (P=0.002) and T2 (P=0.030). Miniscrew implants with lengths of 10–12 mm had the highest success rate (98.0%) compared to other lengths, and this is statistically significant (P=0.035). At T2, lengths of 10–12 mm had significantly (P=0.013) higher success rates (93.5%) compared to 6-7 mm (76.7%) and 8 mm (82.1%) miniscrew implants.Conclusion. Multivariate statistical analyses of 11 variables demonstrate that length of miniscrew implant is significant in determining success.

The Impact

The conventional approach to assessing structural change in regional input – output tables is to measure the impact of coefficient change on the estimation of outputs and multipliers. The methods developed and tested in this paper focus exclusively on the coefficients. Univariate and multivariate statistical analyses can be used to identify and measure various types of changes ranging from coefficient instability to changes in interindustry relationships as a system. A distinction is made between structural changes in input relationships and those in output relationships. The methods are tested by using Washington State data for the years 1963 and 1967. The results are compared with previous analyses of change in these data.

AbstractObjective:A mechanism was initiated for conveying quality improvement (QI) results to paramedics as a means of improving chart documentation in difficult-to-correct areas. This study examines the impact of this QI feedback loop on charting, resuscitation rates from cardiac arrest, endotracheal intubation (ETI) success rates, and trauma scene times.Design:Paramedic trip sheets were reviewed before and after the institution of the QI feedback hop in this interrupted time series design.Setting:The New Castle County, Delaware, Paramedic Program.Participants:All New Castle County paramedics participated in the study.Interventions:In January 1990, the medical director began to circulate a QI summary among the paramedics in an effort to improve performance and chart documentation. The summary focused on the management of respiratory distress or arrest, cardiac arrest, and major trauma. The success rate for ETI was compared with the rate of field resuscitation from cardiac arrest, the percentage of unjustified prolonged trauma scene times (longer than 10 minutes), and the percent compliance with minimum endotracheal intubation documetation (ETID) requirements from a six-month period before institution of the QI feedback mechanism with data obtained from a six-month period after the program had been operational for one year.Results:Comparing results from before with after the initiation of the QI program, the ETI success rate was 273 of 295 (92.5%) before and 300 of 340 (88.2%) after (X2 = 3.04, p <.1, ns); field resuscitations totaled 26 of 187 (13.9%) before and 44 of 237 (18.6) after (X2 = 1.40, p <.25, ns); ETID rate was 249 of 295 (84.4%) before and 336 of 340 (98.8%) after (X2 = 44.24, p <.001), and unjustified prolonged trauma scene times were 69 of 278 (24.8%) before and seven of 501 (1.4%) after (X2 = 320.5, p <.001).Conclusion:The use of QI feedback had little effect on psychomotor skills such as the ETI success rate or resuscitation rate, but had a dramatic effect on chart documentation, as evidenced by ETID rate, and behavior, as evidenced by the reduction in prolonged trauma scene times. The use of QI feedback is recommended as a means of correcting charting deficiencies or modifying behavior.

The aim of this study was to review the literature and evaluate the failure rates and factors that affect the stability and success of temporary anchorage devices (TADs) used as orthodontic anchorage. Data was collected from electronic databases: MEDLINE database and Google Scholar. Four combinations of term were used as keywords: “micro-implant”, “mini-implant”, “mini-screw”, and “orthodontics”. The following selection criteria were used to select appropriate articles: articles on implants and screws used as orthodontic anchorage, published in English, with both prospective and retrospective clinical and experimental investigations. The search provided 209 abstracts about TADs used as anchorage. After reading and applying the selection criteria, 66 articles were included in the study. The data obtained were divided into two topics: which factors affected TAD success rate and to what degree and in how many articles they were quoted. Clinical factors were divided into three main groups: patient-related, implant related, and management-related factors. Although all articles included in this meta-analysis reported success rates of greater than 80 percent, the factors determining success rates were inconsistent between the studies analyzed and this made conclusions difficult.

The Impact

Blood sampling for self-monitoring of blood glucose is difficult for the elderly with low dexterity. We developed and tested the utility of an automatic puncturing and sampling (APS) system as a part of an automatic SMBG device, but success rates of securing sufficient blood volume was low (61.9%). Thus, the squeezing condition was changed to increase its success rate. The aim of this study is to investigate the impact to the amount of bleeding by making changes to the squeezing condition. In our previous experiment, blood sampling was performed simultaneously with squeezing, whereas the present study tested blood sampling after squeezing. This method increased the success rate (75%) among eight subjects who had a low success rate (25%) in the previous experiment using the APS system.

The Impact

A natural experiment contrasted the social relationships of people with intellectual disabilities ( n = 110) before and after they moved from congregated settings to either personalized accommodation or group homes. Contrasts could also be drawn with individuals who had enduring mental health problems ( n = 46) and who experienced similar moves. Face-to-face interviews were conducted in each person’s residence on two occasions approximately 24 months apart. Multivariate statistical analyses were used to determine significant effects. Greater proportions of people living in personalized settings scored higher on the five chosen indicators of social relationships than did persons living in grouped accommodation. However, multivariate statistical analyses identified that only one in five persons increased their social relationships as a result of changes in their accommodation, particularly persons with an intellectual disability and high support needs. These findings reinforce the extent of social isolation experienced by people with disabilities and mental health problems that changes in their accommodation only partially counter.

Introduction: Prehospital tracheal intubation of a difficult airway is challenging for paramedics. Thus far, the potential role of video laryngoscopes for this purpose has not been confirmed. Therefore, this study aimed to determine the impact of different types of video laryngoscopes on the success rate and time to intubation by paramedics. Methods: This is a prospective, randomized, crossover manikin study involving 18 paramedics. Participants performed intubation on a difficult airway in a high-fidelity manikin using Pentax-AWS®, Glidescope®, and King Vision® (with two blade types). Time to intubation and success rate of intubation were determined. Participants also rated the best glottic view and reported their preferences of devices. Results: In a difficult-airway scenario, the median time to intubation with Pentax-AWS® was 22.9 s (interquartile range, 19.5–24.9 s), which was significantly shorter than using other devices. There were no significant differences in the time to maximal exposure of the vocal cords between four devices ( p = 0.156). The time to insert the endotracheal tube with Pentax-AWS® and King Vision® with a guide-channel blade was significantly shorter than that with the other two devices (all, p < 0.05). Pentax-AWS® and King Vision® with a guide-channel blade showed higher success rates than the other two devices ( p = 0.04). With regard to device preference, 14 participants preferred Pentax-AWS® among all devices analyzed. Conclusion: Pentax-AWS® could be an appropriate device for paramedics in cases of difficult airways, with high success rate.

Purpose – The purpose of this paper is to examine why culture is the cause of such widespread failure in mergers and acquisitions (M&A) and explore ways to improve their success rate. Design/methodology/approach – Review of some prominent “failed” mergers for evidence of the influence of cultural factors. Findings – It was found that M&A tended to be more successful where cultural factors were made a priority early in the process and where transparent and two-sided dialogue about culture took place up and down both organizations. Originality/value – Although the impact of culture in M&A is a topic that has been covered before, this review identifies some new approaches to improving M&A success rates.

Purpose The purpose of this study was to determine the attendance and success rates for seniors in voice therapy, identify any contributing patient-related factors, and compare results to existing findings for younger patients. Method This retrospective study included information from the voice records of 50 seniors seen by the same speech-language pathologist in a private practice. Analysis of attendance and outcome data divided participants into 6 groups. Outcomes for Groups 1–3 (64% of patients) were considered successful (positive voice change), while outcomes for Groups 4–6 (36% of patients) were considered unsuccessful. These data were compared to similar data collected for younger adults in a previous study. Results The attendance and success rates for seniors in this study were higher than those previously reported for younger patients. Further consideration of patient factors revealed that reports of increased stress, Reflux Symptom Index scores > 13, and higher Voice Handicap Index functional subscale scores were significant in distinguishing between patients in the successful and unsuccessful treatment outcome groups. Conclusions The relatively high attendance and success rates among this sample of seniors suggest the desire to achieve voice improvement does not diminish with age, and chances for success in voice therapy among nonfrail seniors may be greater than for younger patients.
